Since Smart phones, we have always rented a SIM from Sharon. I will probably buy from UTS when we arrive. Do you just call them to top off if you run out of time? We really don't use the phone much--mostly for reservations and a quick check home. Or if my credit card company decides to send me an urgent message!!!! I almost forgot--- changing airline reservations

Maybe I'm very low maintenance but I have to do nothing to be able to make calls home from my own cell...and receive them (or return the call) when on wifi at SBR. I just inform everyone to use email instead of text and there is no issue.

I would think it overkill to rent a phone or get a sim just for reservations (use Skype) and on road calls....
